【正文】 I 摘 要 本設(shè)計(jì)主要闡述了年產(chǎn) 萬(wàn)噸鎂質(zhì)耐火材料廠在設(shè)計(jì)中的重大問(wèn)題以及方案的選擇。 首先，根據(jù)設(shè)計(jì)要求，設(shè)計(jì)原則，產(chǎn)品的種類(lèi)（鎂磚，鎂鋁磚，鎂鉻磚）及工廠的規(guī)模和生產(chǎn)方法，確定出生產(chǎn)的工藝過(guò)程，原料配比和顆粒的組成，各個(gè)車(chē)間的工作制度等。 其次，進(jìn)行物料平衡計(jì)算，主機(jī)平衡計(jì)算，根據(jù)計(jì)算結(jié)果進(jìn)行設(shè)備選型。再根據(jù)設(shè)備在工廠中的安裝要求及檢修要求進(jìn)行車(chē)間房布置。 再次根據(jù)主機(jī)設(shè)備的需要對(duì)輔助設(shè)備進(jìn)行選擇。選擇出合理的輔助設(shè)備并且確保主機(jī)設(shè)備正常高效運(yùn)行。 接著，對(duì)初步設(shè)計(jì)完成后的每個(gè)車(chē)間視其自身的特點(diǎn)進(jìn)行合理的技術(shù)經(jīng)濟(jì)編制。 最后，對(duì)設(shè)計(jì)中遺留的的問(wèn)題進(jìn)行了討論。另外本設(shè)計(jì)中穿插有設(shè)備的外形尺寸圖和工藝布置圖，便于閱讀和理解。 關(guān)鍵詞 ：工藝設(shè)計(jì) ,鎂磚 ,鎂鋁磚 ,鎂鉻磚 II Abstract This design describes the major issues of an annual 35,000 tons output of magnesia refractories plant in the design mainly and explained choices of the program. First, according to design requirements, design principles, product type (brick, magnesia brick, magnesiachrome brick), the plant size and production methods,it is to determine the production process, the proportion and position of particles, each workshop work system and so on. Second, it is to work out the material balance, and the host balance. And then, according to the result, it is matching the equipment type and it is arranging the factory according to installation of requirement and examination in the factories. After that, it is to draw up the reasonable technology and economy due to the each workshop39。s self character after finishing the first design. Finally, it is to discuss the missing issues of design. Moreover, there are papers of equipment39。s appearance and arrangement in the design. It is convenient to read and understand. Key words: process design, Magnesia brick,Magnesium aluminum brick,Magnesia chrome brick III 目 錄 1. 文獻(xiàn)綜述 ........................................................ 1 原料 ......................................................... 1 鎂石 ..................................................... 1 2. 結(jié)構(gòu)與形態(tài) .................................................... 2 鎂砂 ..................................................... 3 各種磚的介紹 ................................................. 3 鎂磚 ...................................................... 3 鎂鋁磚 .................................................... 4 鎂鉻磚 .................................................... 5 結(jié)合相 ....................................................... 6 硅酸鹽 .................................................... 6 鎂的氧化物和鐵酸鹽 ........................................ 6 尖晶石結(jié)合物 .............................................. 6 發(fā)展前景 ..................................................... 7 2 設(shè)計(jì)原始數(shù)據(jù)及資料參數(shù) .......................................... 8 設(shè)計(jì)題目 ..................................................... 8 規(guī)模及產(chǎn)品方案 ............................................... 8 設(shè)計(jì)參數(shù) ..................................................... 8 主要材料及動(dòng)力來(lái)源 .......................................... 10 設(shè)計(jì)的原則和要求 ............................................ 10 3 生產(chǎn)方法和工藝流程 .............................................. 11 概述 ........................................................ 11 鎂質(zhì)耐火材料的原料 .......................................... 11 制品的使用質(zhì)量要求及標(biāo)準(zhǔn) .................................... 13 提高產(chǎn)品質(zhì)量的途徑 .......................................... 15 直接結(jié)合 .................................................... 16 生產(chǎn)方法的選擇 .............................................. 17 4 工藝計(jì)算 ........................................................ 22 物料平衡計(jì)算的目的 .......................................... 22 IV 物料平衡計(jì)算 ................................................ 22 計(jì)算過(guò)程說(shuō)明 ............................................ 22 各種磚型物料平衡計(jì)算 .................................... 22 主機(jī)設(shè)備選型 ............................................... 34 主機(jī)平衡計(jì)算 ............................................ 34 原料倉(cāng)庫(kù)、料倉(cāng)的計(jì)算 ........................................ 42 原料倉(cāng)庫(kù) ................................................. 42 橋式抓斗起重機(jī)搬運(yùn)能力及計(jì)算 ............................. 43 成品倉(cāng)庫(kù)的面積確定 ....................................... 45 供料倉(cāng)計(jì)算 ............................................... 45 5 熱工計(jì)算 ........................................................ 50 隧道干燥器的選型計(jì)算 ........................................ 50 隧道干燥器數(shù)量的計(jì)算 ..................................... 50 干燥車(chē)數(shù)量的計(jì)算 ......................................... 50 隧道窯選型計(jì)算 .............................................. 51 窯的規(guī)格和臺(tái)數(shù)的確定 ..................................... 52 窯車(chē)數(shù)量的確定 ........................................... 53 6 輔助設(shè)備選型 .................................................... 54 給料、計(jì)量設(shè)備 .............................................. 54 輸送設(shè)備 .................................................... 54 除鐵設(shè)備 .................................................... 55 7 車(chē)間工藝布置 .................................................... 56 工藝布置一般要求 ............................................ 56 破粉碎車(chē)間的布置 ............................................ 57 粉碎、磨碎混合工段 .......................................... 57 工段的布置 ............................................... 57 圓錐破碎機(jī)的布置 ........................................ 57 管磨機(jī)的布置 ............................................ 57 斗式提升機(jī)與篩分設(shè)備的布置 .............................. 58 混合設(shè)備的布置 .......................................... 58 成型車(chē)間的布置 .............................................. 58 干燥、燒成車(chē)間布置 .......................................... 58 V 成品庫(kù)布置 .................................................. 60 8 技術(shù)經(jīng)濟(jì)指標(biāo) .................................................... 61 總結(jié) .............................................................. 64 參考文獻(xiàn) .......................................................... 65 致謝 ............................
